for any damage resulting from improper use.
Use of this instrument is strictly prohibited in:
•
explosion-proof environments,

General hazards
General hazards arise from:
•
covering the ventilation slots
•
an insufficient distance from the back of the unit to the
wall (see Section 4 "Putting into operation“).
•
touching the injection head and the FID (risk of burning).
•
improper storage of gas cylinders.
•
inadequate installation of connections to gas cylinders.
Apart from authorized maintenance personnel, no one is
allowed to remove any safety devices and covers.
Touching live parts may result in fatal injury!
Electrical danger
Before connecting the unit to power make sure that the opera-
ting voltage shown on the serial plate agrees with the mains
voltage.
The power plug may only be inserted into a socket
with grounded contact. Its protective effect may not
be suppressed by an extension line not having a
ground wire.
Warning:
a) Any interruption of the ground wire inside or outside of the
unit or a disconnection of the ground wire may cause
potential problems. Deliberate tampering is prohibited.
b) When opening covers or removing parts, unless this can
be done by hand, live parts may be exposed. Bear in mind
that connecting parts may also be live.
